Descripción

Amino Acid Sequence

Phe-Ser-Leu-Leu-Arg-Tyr-NH₂ trifluoroacetate salt

Application

FSLLRY-NH2 trifluoroacetate salt has been used as a protease-activated receptor 2 (PAR2) inhibitor to test its effects on urinary tract infections (UTIs) in a murine model. It has also been used to study the clinical itch datasets from phase 3 clinical trials for moderate-to-severe AD in atopic dermatitis (AD)-associated acute itch flare mice modelin rats.

Biochem/physiol Actions

FSLLRY-NH2 is a peptide antagonist of the protease activated receptor 2 (PAR2). The peptide blocks agonist induced itching in rodent models. In cell based assays, the peptide inhibits agonist-induced cardiocyte remodeling, and production of cytokines by endothelial cells.

The ability of FSLLRY-NH2 to decrease visceral hypersensitivity (VH) suggests that PAR2 is involved in the maintenance of VH.
